SNAP-LOCK CONTAINER RING AND METHOD.

摘要

The present invention is directed to a carton including a lid and a container having a reinforcing ring that cooperatively engages the top portion of the container in a rib-and-groove snap-lock fit. The reinforcing ring is coextensive with the opening of the container and has a band located on the interior of the container, and exposes no sharp edges. The ring is butted against the inside of the container wall and the top edge of the container wall. An edge of the ring lies on the top edge of the container wall and is inwardly recessed from the wall thus preventing the ring from protruding beyond the container wall and eliminating interference with adjacent containers or the risk of injury to fingers or hands.
